(IWS) |

Wastewater is generated by most
of the water usages in a home. This includes toilet wastes,
kitchen wastes, bath water, and laundry waste. Because wastewater
contains nitrates, phosphates, bacteria and viruses, it must be treated
and disposed of in a way that will safeguard our drinking water supply
and reduce potential health hazards.
Each home not connected to a
central or public wastewater facility, as is common on Maui, must
have and maintain its own wastewater system. A properly functioning
wastewater system disposes of wastes and treats the water so that it
will be safe when it reaches recreational waters or drinking water
tables.
Cesspools
and
Septic Systems
Septic
tanks are usually newer, made of plastic, fiberglass or concrete
(less common) and have two covers. Cesspools are older, made of
concrete and have one cover.
